Question

A particle is rotating on a circular path with initial angular velocity 2 rad/s and angular acceleration of 1 rad/s² then find it's net acceleration in m/s² after 2s if radius of path is 1m?

Answer 1

Given,

The radius of the circular path r = 2m

Angular velocity \(\omega\) = 4 rad/s

Angular acceleration α is rate of change of angular velocity 

α = \(\frac{\omega}{t}\)

Here in the question, the angular velocity is given as constant.

Therefore,the angular velocity is not changing with time

Thus,angular acceleration α = 0
